I see that you added 1.04 US to the table of supported firmwares in the
installation instructions here:
http://www.rockbox.org/twiki/bin/preview/Main/ManualRockboxInstall.
Please note that those instructions relate to patching the firmware with
fwpatcher.exe, and therefore, only firmware versions that are supported
by fwpatcher.exe should be included in that table. I've removed the
reference to 1.04 U.S.
